"A sound introduction to a crucial doctrine. Emery's prose is scholarly yet widely accessible, at once traditional and constructive" (Themelios).

Representing the highest quality of scholarship, Gilles Emery offers a much-anticipated exploration to Catholic doctrine on the Trinity. His extensive research combined with lucid prose provides readers a resource to better understand the foundations of Trinitarian reflection and addresses all who wish to benefit from an initiation to Trinitarian doctrine.

The path proposed by this introductory work comprises six steps-from liturgical and biblical ways for entering into Trinitarian faith to the creative and saving action of the Trinity. The book concludes with a doctrinal exposition of the "missions" of the Son and Holy Spirit, that is, the salvific sending of the Son and Holy Spirit that leads humankind to the contemplation of the Father.

"Trinitarian doctrine is not easy, but Emery (with his translator) has rendered it intelligible and attractive . . . Exegetes, theologians, historians, and liturgists alike will find the Trinity related to their discipline. Most importantly, The Trinity will prepare its readers to enter higher levels of discussion about the Trinity." -Sacra Pagina
